Abstract

The present inventors recognized a need to leverage the data from Advanced Metering Systems (AMIs) in the management of electrical outages. To address this and/or other needs, the present inventors devised, among other things, systems, methods, and software that not only intelligently filter and communicate AMI outage data to Outage Management Systems (OMSs), but also facilitate communications between OMSs and multiple types of AMI systems. One exemplary system includes an outage management module that receives AMI outage data in the form of “last gasp” messages from meters and determines whether the OMS is already aware of a power outage associated with those meters. If the OMS is already aware of an outage associated with these meters, the outage management module excludes the outage reports from its communications with the OMS, thereby preserving its capacity to handle new outage information and overcoming a significant obstacle to using AMI data within OMSs.
